3dsmax hangs with curvature map as a texture in the extraTex slot

[hardrock_ram]

If I try to use VRayCurvature in the VrayExtraTex render element, the program hangs. Is this a bug, or is it simply not possible?
I can of course render it out seperate, so its not really an issue. I just would like to know

EDIT: There might be a problem with my scene instad ... Sorry for posting uneccessary
